MACHINE FOR MANUFACTURING RAILWAY-TIES.

SPECIFICATION forming part Of Letters Patent No. 591,838, dated October 19, 1897.

Application filed July 16,1895. Serial No. 556,184. (No model.)

To all whom it may concern:

Be it known that I, GRANTGEEEN, J r., a citizen of the United States, and a resident of New York, in the county of New York'and State of New York, have invented certain new and useful Improvements in Machines for Manufacturing Railway-Ties, of which the following is a specification, reference being had to the accompanying drawings, forming a part thereof, in which similar letters of reference indicate corresponding parts.

This invention relates to manufacture of railway-ties and the object thereof is to provide a machine which will saw ties and also hew the sides thereof, it being well known that ties having hewn surfaces are much more durable and also more valuable than those having surfaces and sides formed by a saw.

The invention is fully disclosed in the following specification, of which the accompanying drawings form a part, in which Figure 1 is a side elevation of my improved machine; Fig. 2, an end elevation thereof; Fig. 3, a plan view of a cutter which I employ. Fig. at is a plan view of the entire machine. Fig. 5 is a side elevation of the machine. Fig. 6 is an end view of the machine, looking in the direction of the arrow 6.

Fig. 7 is a section, on a larger scale, on line 7 7 of Fig. at. Fig. 8 is a view of the cutter or hewer.

In the practice of my invention I employ an ordinary frame consisting of bottom side pieces A and cross-pieces B, the ends of a part of which are shown in dotted lines in Arranged longitudinally of the main frame and at each side thereof are side frames, the ends of which are shown in Fig. 2, and consist of vertical standards 0, top cross-bars D, and longitudinal side top plates E, one of which is shown in full lines in Fig. 1, and the ends of which are shown in dotted lines in Fig. 2. Mounted between these longitudinal frames are cross-bars F, and rails G, which support a truck provided with wheels ll, on which is mounted a carrier K, provided with side arms or plates L, which extend over the tops of the sides of the longitudinal frames, as shown in Fig. 2.

Connected with the under side of the carrier K is a rack-bar M, (clearly shown in Fig. 1,) which is operated by a pinion m, mounted on a shaft m, which extends transversely of the machine and is provided at its outer end with a wheel N.

The form of the reversing mechanism illustrated in Fig. 5 of the drawings, showing two pulleys for driving the carrier in opposite directions, may be actuated by any suitable means.

Mounted in each of the longitudinal frames at opposite sides are saws O,'by which the ties are formed of the required size, and each of these saws is mounted on a shaft 0, provided with a wheel 0 and arranged beneath the shaft m is a shaft P,which is movable, and provided with a belt-wheel P, which is adapted to be thrown into and out of contact with the wheel N by a lever p, and mounted on the shaft P is also a power-wheel 19.

,As shown in the drawings, the longitudinal frame which supports the saw onthe lefthand side of the machine is laterally movable or may be moved toward or from the center of the machine, the object of this arrangement being to adjust one side of the machine provided with its saw and cutter, so as to form ties of different widths and thicknesses. This result is accomplished by means of a shaft R, (shown in dotted lines in Fig. 1,) on which, at regular intervals, are mounted pinions R, which are-adapted to operate in connection with rack-bars S, as shown in dotted lines in Fig. 2, which are secured transversely of the bottom of the longitudinal frame. The shaft R. has mounted thereon, at one end, a ratchet-wheel or pinion T, and also a vertical lever U, to which is pivoted a crank-lever U, provided with a rod U which extends downwardly and operates in connection with the ratchet or pinion T, as will be readily understood, and by means of the leverU the shaft B may be rotated or revolved in such manner that the pinions R thereon will operate the rack-bars S, one of which is provided for each pinion and each of which,as hereinbefore stated, is connected with the bottom of the longitudinal frame in such manner as to move the longitudinal frame or the center portion thereof, which carries the saw and the cutter, toward or from the center of the machine. The longitudinal frame, on this side of the machine, is divided at W, forming a central portion W, and this central portion is laterally movable while the end portions will remain stationary, as will be readily understood, or if desired the entire side frame on this side of the machine may be moved toward or from the center, as hereinbefore described.

Mounted rearwardly of the saws, on each of the longitudinal frames, are cutters a, as shown in Fig. 1, which consist of central blocks 6, and the cutting knives or blades cl, which are rigidly secured to the opposite sides thereof and the cutting edges of which project in opposite directions, and these outters are mounted on vertical shafts on the lower ends of which are mounted pulleys g, which are adapted to be driven or operated by power-belts, connected with the engine by which the machine is operated, in any desired manner.

Fig. 7 of the drawingsrepresents a detail view of two cross-pieces B B in section, two rack-bars S S in section also, in place, partially inclosed within the cross-pieces B B, two pinions R R, splined upon the shaft R, in'mesh with the two rack-bars S S, and two vertical standards 0 0 broken off near the top, which support the top plates E E. (Shown in Fig. l of the drawings.)

In Fig. 8 of the drawings is shown my modified form of cutter disk orhead. The numeral 2 represents the case or holder for the cutters 3, the edges of which project through slots in the disk or head. The said cutters 3 are held in the cases by clamps 0 or screws such as are in ordinary use for similar purposes.

The numeral 1 (shown in Figs. 1, 5, and '7 of the drawings) represents the platform which supports the lower end of the standards 0 C, and upon the tops of which the top plates E E rest.

In operation, as will be understood, the shifting device, consisting of the shaft P, the pulley P, mounted thereon, and the lever 19, connected therewith, is operated so as to bring the pulley P into contact with the wheel N, by which the carrier is operated.

In Figs. 1, 2, and 4 I have shown the earriage driven from the pulley P, which is constantly rotated in one direction to drive the carriage forward by any usual or well-known means, and in Fig. 4 a modification wherein the pulley P may be rotated in either direction by either one of the two pulleys shown, which pulleys are driven in the necessary di rection by any usual or well-known means from a suitable source of power, and in both cases the pulley P is mounted upon a carriage so as to be shifted into or out of frictional contact with the pulley N bymeans the lever 19 and its link.

The wood from which the tie is formed is placed upon the carrier A, and the saws 0, being revolved by the shafts 0, will cut the sides thereof, or form the tie of the required width and thickness, and as the tiepasses through between the cutters b, said cutters hew or cut the sides thereof, as will be readily understood, and it willbe also understood that all of the sides of the tie may be similarly operated upon by passing it through the machine a second time.

Whenever it is desired to shift the position of the laterally-movable frame, as hereinbefore described,so as to accommodate the machines to ties of difierent widths or thicknesses, the lever U is operated and the shaft R, provided with the pinions R, will operate to adjust the movable portion of the frame, with which the shaft and pinions are connected, laterally or toward or from the central portion of the machine.

It will .be understood that the rack-bars S are connected with the bottom of the vertical standards 0 in the construction shown in the drawings, but these elements of construction are not material, and said rack-bars may be connected with said movable frame in any desired manner, and it is apparent that many changes in the form, construction, combination, and arrangement of the various parts of my improved machine may be made with- -out departing from the spirit of my invention or sacrificing its advantages and I therefore reserve the right to make all such changes in theform, construction, and arrangement of the various parts'as fairly come within the spirit of my invention.

In operating my machine, it is obvious and manifest, from the construction shown upon .Sheet 1 of the drawings, that the carrier may be readily moved in opposite directions by revolving the transverse shaft m and the pinion m, fixed thereon, which meshes with the longitudinal rack-bar secured to the under side of the carrier. Furthermore, it is apparent that the movable side frame may be moved to and from the central base-frame by revolving the shaft R and the pinions R, fixed thereon, which mesh with the rack-bars S S, secured to the bottom of the said movable side frame.
